I just joined, so I ask for a bit of patience please. I have purchased my dinar over the past 9 months or so from 3 different dealers. Each has sent me my dinar with a certificate of authenticity, the information that it has been checked through a Delarue machine and when I received it I did a check on each of the notes (25K) for their security features which appear to all be there. Two of my dealers were US based and registered with UST and the other a Canadian based firm registered with their equivalent. Is there anything else I can do to to confirm authenticity? The last thing I want is to go to the exchange and have them claim what I have is counterfeit. I just don't think I could take that after all we have been through. Thanks!
